James Oliver says he is an alien that has come back from the year 6491

Who is 'time traveller' James Oliver?

The man who gave his name as James Oliver said a volcano underneath Yellowstone national park will devastate America.

In a video posted online, he said: "I would be very cautious about the Yellowstone volcano.

"As all of you know it's overdue by about 600,000 years and an eruption that size would devastate the entire United States.

"And the biggest issue about an eruption like this is that it will produce a massive amount of ash into the atmosphere and the way your transportation mechanisms work - if you were to drive or fly through one of these ash storms, your engines will be ruined.

The test appeared to consist of a man, who was wearing a hoodie jumper, looking at a laptop while asking the so-called time traveller a series of questions.

What reason did he give for being 'trapped' on Earth?

Oliver further claimed he was trapped on Earth after the super blue blood moon interrupted a transmission on his ship.

Further explaining his bizarre situation he added: “I’m from a planetary system that is not this one, I’m sorry I’m being very vague I cannot be specific, it’s company procedure.

“Essentially what I am is I’m sort of like an archaeologist.

“What had happened was the geological event had disrupted the signal somehow and I got backchannels flooding into my system from outside sources and it essentially fried the operating system of my ship, which means that I am stuck here until another research team lands on this planet.

“I could be here a few more days, I could be here a few more years, decades, centuries.

"I really don’t know. I haven’t gone much into the future from here.”
